SWWMNLHFII'ER FOR YARN-SPOOMNG MACHINES.

PIIGIFIGAZIJIIDN forming part of Letters :Patent No. 640,474, dated January 2, 1900.

Application tiled April 27, 1898. Serial No. 679,013. (No model.)

To r/JZ wiz/ont it may concern.'

Be it known that I, FRED LACEY, a citizen of the United States, residing at Valleyiield, in the county of Beauharnois and Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Spool-Lifters for Yarn-Spooling Machines, of which the following is a specification, reference being had therein to the accompanying d rawin gs.

Among the operations to which yarns are subjected in the process of manufacture is that of spooling, in which the yarns from a number of cops or bobbins successively are wound onto a large spool, the last end of the yarn from a cop or bobbin as the latter becomes exhausted being united to the beginning of the yarn on a fresh cop or bobbin, and so on in succession until the spool is full. Froin 'time 'to time also in the course of the spooling it becomes necessary to arrest the winding operation and to break the yarn which is being wound from a cop or bobbin onto the spool for the purpose of removing from such yarn a knot or the like, the broken ends afterward being united by the spoolertender by means of a carefully-tied knot and the winding being allowed to proceed. The spools onto which the winding is effected are mounted upon rotating spindles, and Whew ever it is desired to effect the uniting of two ends of yarn-that is to say, whenever one cop or bobbin becomes exhausted and a fresh one is substituted-or a knot has to be re moved it is necessary for the spooler-tender to restrain the spool from rotation until after theknothasbeen tied. Ordinarilyitbecomes necessary for the spooler-tender to hold the spool from rotating with its spindle by his hand, and this necessity renders it more or less inconvenient for him to effect the tying of the knot. It is preferred in some cases that the tying sha-ll be effected by the formation of a weavers knot, which in some respects is the best for the purpose and occasions the least trouble in weaving; but this knot re quires the use of both hands and is a difficult one to tie when the duty of holding the spool from rotation by hand devolves also upon the spooler-tender.

The object of the invention is to provide a simple and convenient device by means of which the spool may be lifted out of driving engagement with its spindle whenever it is desired to arrest the rotation of the spool for the purpose of tying a knot or for any other purpose, the said device operating to hold the spool lifted while the spooler-tender performs the necessary operations, both the hands of the spooler-tender being left free for such operations.

The invention will be described first fully with reference to the accompanying drawings, in which I have illustrated the best embodiments thereof which I have yet contrived, after which the essential and distinguishing characteristics of the invention will be more particularly pointed out and distinctly dclined in the claims at the close of this speciication.

ignates the spindle-driving drum, and 5 5 designate the bands passing around the said drum and also around the spindle-whirls. 6 designates the supporting-rod for the bobbin or cop holders 7 7, and 8 8 designate yarn guides or clearers, which are mounted upon the supporting-rod 9, the usual spool-box being designated 10. The frictional drivingdisks upon the spindle are designated 11 11, and 12 12 designate the spools which are mounted on the spindles. which are being wound are shown as proceeding from the bobbins 14 14 contained in the holders 7 7 and passing over the rod 9 and through the yarn guides or clearers 8 8 to the said spools 12 12. 15 15 designate small frames or castings, the same being fastened by means of bolts or screws to the front of the spool-box 10, one of such frames or castings usually being located adjacent to each spindle. 16 designates a small hand-operated lever which is connected pivotally to each frame or casting 15 and standing in a vertical position. .The said lever is connected with the said frame or casting by a pivotal pin or rivet 17, which is applied to the said frame or casting near the lower end of the latter, the said pin or rivet being headed so as to retain the lever thereon. The lower end of the lever 16 is provided with a projection 18, which may be constituted bya roller that is journaled on the said lower end of the lever, the said roller or other projection extending under the lower head of the spool 12, which is carried by the spindle 11 in front of the stand 15. The main portion of the lever extends upward from the pivotal pin 17, and near the upper end of the frame or casting 15 said portion of the lever passes through a slot or opening 1 9 in the frame or casting, the said upper end of the latter being bent forward, so that the bar 2O above the said slot or opening 19 lies in front of the plane occupied by the lever 16. The bar 2O serves as a keeper for the upper Vportion of lever 16, and the extent of the lateral swing of said lever is limited by the ends 21 21 of the slot or opening 19. In the upper side of the bar 2O is a notch or depression 22 to receive the pin 23, projecting from thelever 16 over the bar 20, the remainder of the upper surface of the said bar being concentric, or substantially so, with the pivotal pin or rivet 17. The lever is slotted longitudinally at 24, where the pivotal pin 17 passes therethrough, so that the weight of the lever 16 will cause the pin 23 to rest and slide on the uppersurface of the bar 2O until in the movement of the lever the notch or depression 22 is reached, when the lever will drop, the pin entering into the said notch or depression, and thereby the lever will be locked in the position which it then occupies until the pin is raised or pressed out of the notch or depression. The upper end of lever 16 projects abovethe top of frame or casting 15 and is conveniently shaped, as by flattening and widening the same, as represented in Figs. 3 and 4, to fit the same for The yarns 13 13- being taken hold of or pressed against by the ngers of one of the spooler-tenders hands. The lever is unbalanced in consequence of the fact that the part thereof to which roller 18 is applied projects to one side of the center of gravity of the lever, so that whenever the pin 23 is disengaged from the notch or depression in the bar 2O of the frame or casting 15 the lever gravitates into the position in which it is represented at the left in Fig. 1 and in Fig. 3, such being the normal position of the lever, and being occupied by the latter while the winding is proceeding in proper manner on the spool carried by the spindle with which the lever is associated in the machine. When it is desired to stop the rotation of such spool, the hand-lever 16 is pushed over until the pin 23 drops into the notch or depression 22, thereby raising the spool out of driving engagement with the spindle, the hand-lever being held locked in position to keep the spool raised until the pin 23 has been disengaged from the notch or depression 22 and the lever has been allowed to swing back into its normal position. The position of hand-lever 1G relatively to the spindle carrying the spool with which it coacts is such as to renderit convenient for the spooler-tender after having moved the said hand-lever by one hand and thereby stopped the spool to employ the same hand for the purpose of raising the spool and turning the latter to find the end of the yarn that is wound thereon.

In Figs. 1 to 3 the main portion of the handlever 16 is straight and extends upward in line with the pivot of the lever. In this case the distance of the roller 18 laterally from the said pivot compels the stand to be mounted in a position intermediate the spindle with which it is associated in use and the next spindle. This is not so convenient forAthe spooler-tender as it would be to have the casting and main portion of the lever located immediately in line with the corresponding spindle and at the rear of such spindle. This latter arrangement may be secured, if desired, by giving a bent or angular form to the handlever, so as to dispose the handle of the lever and the roller 18 in line with each other. An arrangement embodying this last-mentioned feature is shown in Figs. 5 to 8. Figs. 5 to 9, in addition, illustrate another device which may be utilized for the purpose of detaining or holding the hand lever, which therein is designated 161, in the position which maintains the spool out of driving contact with its spindle. In these igures 25 designates a iiat spring that extends across in front of the upper part of the hand-lever 16 and serves in part as a guide for the said handlever 16. One end` of the said spring 25 is fastened, as by means of a rivet 26 or other securing device, to a raised portion 27 on one side ot' the frame or casing 26. The other end of said spring plays in a notch 28, formed in a corresponding raised portion 29 on the other sideof the frame or casing. At an in- IOO IIO

cenare termediate point in its length the spring` is bent so as to form a projection, as SO, estending into the path of movement of the handlever. This projecting portion 30 of the spring serves to hold the hand-lever from returning` after the saine has been moved over to the right-hand side into the position in which it serves to raise the spool out of driving' engagement with its spindle.

As will be apparent from the foregoing; the operative portion ot the spool-lifter consists of a single hand-operated lever gravitating normallyinto an inoperative position, the said lever occupying a vertical or upright (or substantiallysuch) posit-ion near the spindle with which it is associated in use and having its upper portion extended into position adjacent to the upper ends of the spindle and spool to enable such portion to be acted upon by t-heiing'ers otthehand ofthe spooler-tender while such hand is bearingI upon the top of the spool or just above the same and the lower portion of the hand-lever havin g a projection which is offset laterally with respect to the pivot of the hand-lever to engage with Ithe spool and raise it in the movement of the hand-lever. lilith the said hand-leveris combined a means of df-itaining` or holding; the same in its abnormal position to keep the spool raised ont of driving' engagement with the spindle.

its will be obvious, instead of relying` upon gravity for the purpose of causing` the handlcver 15 to assume and retain its normal inoperative position l may utilize a spring,l connected with the said hand-lever.

Figs. 10, 11, and l2 illustrate a modification in which the projection on the lower end of the hand-lever (therein designated 162) is in the form of a forli, (designated 31,) the said fork being held to the hand-lever by means of a rivet or the like, as 32, and having', if desired, capacity to swivel on the said rivet. The arms of 'the lifter-fort: project forwardly on opposite sides ot the spindle and beneath the position of the lower spool-head. This fork may be applied to any of the forms of the hand-lever, including` the double form of such lever, which is shown in Fig. 13. rlhe latter form has been devised with the idea in view of enabling one hand-lever (here designated 163) to serve for use in connection with two adjacent spindles. lthas oppositely-projeeting,I arins,each carryinga roller 18 or a fork 231. One arm and its roller or fork are intended to coact with the spool on one spindle and the otherarm and its roller or fork are intended to coact with the spool on an adjacent spindle, This form of hand-lever will occupy normally an intermediate position, with both its rollers, forks, or other .spool-raising,` projections depressed out ot engagement with the spools. lt may be swung in either direction from its normal intermediate position, according as it is desired to elevate the spool at the right or that at the left, and is provided with a detent device to hold it in either of its operative or abnormal positions. ln Fig. 13 I have shown the hand-lever slotted at 2t, as in Figs. 1 to 3, the bracket or stand 15 being,` substantially the same as in Figs. l to 3, but having a notch 22 at each side of the intermediate position of the upwardly-extending arm ot' the hand-lever.

l claim as my invention-- l. The combination with the spindle of a yarn-spooling machine of the hand-lever standing` adjacent to the spindle at the rear ot' the latter with its arm extending; upward into proximity to the top ot the spindle and in position to be acted upon by the operatives hand which also tal-:es hold ot' the upper head of the spool on such spindle, the said handlever having,` on its lower portion a projection laterally offset with respect to the pivot of the lever to move upwardly and directly lift the spool on the spindle when the hand-lever is moved by pressure exerted on its upper portion by such hand, substantially as described.

2. rl`he combination with the spindle of a yarn-spooling machine, of the hand-lever standing;` adjacent to the spindle at the rear of the latter with its arm extending upward into proximity to the top of the spindle and in position to be acted upon by the operatives hand which also takes hold of the spool on such spindle, the said hand-lever having on its lower portion a projection laterally oftsetwith respect to the pivot of the lever to move upwardly and directly lift the spool on the spindle when the han d-leve r is turned by pressure exerted on its upper portion by such hand, and also having a detent device to retain it in the position thereof which holds the spool raised, substantially as described.

The combination with the spindle of a yarn-spooling machine, of a hand-lever occupying` normally an inoperative position, movable vertically at its pivot, having its upper portion extended into position adjacent to the top of the spindle to enable it to be acted upon bythe hand of the spooler-tender which takes hold of the spool on such spindle, and having; on its lower portion a projection which engages and lifts the spool on the spindle, the said upper portion of the lever having,r also a projection7 and a fixed bar on the upper sur-- face of which the latter projection rests and moves, the said bar having` a notch or depression which the said projection enters to hold or detain the lever in the position thereof which keeps the spool raised, substantially as described.
